The Canadian Charter of Rights and Freedoms itself does not mention a requirement for unanimous consent. However, the Constitution Act, 1982, in Section 41, outlines the “unanimity formula,” which requires unanimous consent from all provinces and both Houses of Parliament for constitutional amendments related to specific matters, such as changes to the office of the Monarch, the composition of the Supreme Court, or the amendment process itself[3][4].
